Specification of Letters Patent.

Application filed October 15, 1913. Serial N 0. 796,268.

To all whom it may concern Be it known that I, ELMER B. STONE, a citizen of the United States, and aresident of New Britain, in the county of Hartford and State of Connecticut, have invented a new and Improved Padlock, of which the following is a specification.

My invention relates to the class of devices hereinabove mentioned, and an object of my invention, among others, is to-provide a device of simple construction, having means to prevent the surreptitious movement of the bolt to release the shackle.

One form of device embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a view in side elevation of a lock embodying myv invention, with parts broken away to show construction and the shackle being locked. Fig. v2 is a like view but showing the position of the bolt just before its release from the shackle. Fig. 3 is a similar view showing the bolt at the Fig. 4 is a detail view in section through the upper part of the lock on plane passing through the bolt. Fig. 5 is a view lookingat that end of the lock opposite the shackle.

In the accompanying drawings the numeral 8 denotes a case formed preferably of thin sheet metal struck to shape and in two halves united by posts 9 in a manner common to looks of this class. A shackle 10 is pivotally mounted in one corner of the case and has a spring 11 tending to force the I shackle to its open position. A container 12 is located within the case, and is held therein in any suitable manner, being formed from a solid piece of metal bored to receive a cylinder 13, the latter having the usual slot for a key. The cylinder and the container are provided with spring tumblers of ordinary form and construction common to looks of this class, and for which reason said parts are not shown in the drawings and further description is omitted herein, all of the parts thus far described being old and well known.

A bolt recess 14 is formed in the upper part of the container, this recess cutting across and opening into the bore 15 for the cylinder, and a bolt 16 is located within said bolt recess. This construction provides a stop 17 in front of a releasing recess constituted by the back portion of the bolt recess, this stop in fact being formedby' the upper edge of the bore 15. A bolt actuator recess 19 is located in the bolt in position to receive a bolt actuator 20 projecting from the end of the cylinder 13, the'engaglng surfaces of the bolt actuator recess and the bolt being fiat, so that as the cylinder is turned the edges of the actuator pressing against the flat surface of the recess will throw the bolt backward when the cylinder is turned in either direction, this construction and operation also being well known and for which reason a further description is omitted herein.

The cutting away of the bolt to form the Patented Jul 21,1914.

recess19 provides what I term a bolt heel from one side to the other, and a bolt spring I 24; is seated with one end against this inclined bottom of the socket and the other againstthe back of the releasing recess 21',

a pin'25 projecting fromthe bottom of the socket being employed if desired as a means for retaining the spring in place.

The end of the bolt actuator 20 is beveled 01f to form a cam' release 26, engaging a releasing recess 27 opening out of thebolt actuating recess 19, the cam release and the releasing recess being so formed that as the cylinder is turned the bolt will be moved laterally into registration with the releasing recess 21. It will be noted that theforniation of the bottom of the spring socket 22 and the spring pressing against it tends to force the bolt into the position shown in Fig. 1, with its end located opposite the stop 17 when the shackle is locked. From this construction it will be noted that'in the operation of the device when the cylinder is turned the cam release enga ing withthe wall of the releasing recess 21 will, on the initial turning movement of the cylinder, force the bolt laterally so that it will register with the releasing recess 21, and the continued rotation of the cylinder will carry the bolt into said recess, thus disengaging it.

from the shackle. This is an effective construction which Will prevent the surreptitious throwing of the bolt, as by blovvs delivered upon the side of the case, an operation which may be employed in many :torms of padlocks to disengage the bolt from the shackle without the use of a key.

While I have shown and described herein a preferred form of construction of mechanism embodying my invention, this may be changed to a greater or lesser degree and yet be Within the spirit and intent of said invention.

I claim:

1. In a lock, a shackle, a bolt longitudinally movable to engage the shackle and to be released therefrom and also laterally movable to engage a stop, a bolt having a releasing recess formed therein, a stop to prevent longitudinal movement of the bolt, a cylinder, and a projection having a cam release extending into the releasing recess in the bolt and arranged to move said bolt laterally to disengage it from said stop and to move it longitudinally to disengage it from the shackle.

2. In a lock, a shackle, a container having a releasing recess, a stop formed at the entrance of said releasing recess, a bolt with its end located normally opposite said stop but adapted to pass into said recess, means for holding the end of the bolt opposite said stop, a cylinder located in the container, an actuator on the end of the cylinder arranged to move the bolt laterally to disengage it from its stop and longitudinally to disengage it from the shackle.

3. In a look, a shackle, a bolt longitudinally movable to engage the shackle and to be released therefrom and also laterally lnovan able to engage a stop, a stop to prevent longitudinal movement of the bolt, a cylinder, and a projection on said cylinder arranged to move the bolt laterally to disengage it from said stop and to move it longitudinally to disengage it from the shackle.

4. In a look, a shackle, a container having a bolt recess, a part of which constitutes a releasing recess, a bolt located in the bolt recess but with its rear end outside of the releasing recess when the'bolt engages the shackle, means for holding the end of the bolt against the stop formed by the edge of the releasing recess, a cylinder located in the container, and an actuator on the end of the cylinder arranged to move the bolt laterally to disengage it from its stop and longitudinally to disengage it from the shackle.

5. In a lock, a shackle, a container having a bolt recess and a cylinder recess, a to part of the bolt recess also constituting a releasing recess, a stop formed at the edge of the releasing recess, a bolt located in the bolt recess and With its end Without the re leasing recess when the bolt engages the shackle, a spring seated in said releasing recess and thrusting the bolt outward and also in position to engage said stop, a cylinder located Within the cylinder recess, and

an actuator on the end of the cylinder ar- 79 ranged to engage the bolt to move it laterally to disengage it from said stop and longitudinally to disengage it from the shackle.
